Minimum allowable values of energy efficiency and
values of efficiency grade for small-power motors
1 Scope
This standard specifies energy efficiency grade, minimum allowable values of energy
efficiency, target minimum allowable values of energy efficiency, evaluating values of
energy conservation, and test method for small-power asynchronous motors (hereinafter
referred to as “motor”).
This standard is applicable to general purpose motors - small-power 3-phase
asynchronous motor (10 W to 2200 W) powered by 50 Hz & 690 VAC and below voltage;
capacitor running asynchronous motor (10 W to 2200 W); capacitor starting asynchronous
motor (120 W to 3700 W), double-value capacitor asynchronous motor (250 W to 3000 W);
and motor (6 W to 550 W) for air conditioning fan in room etc.
2 Normative and Quoted References
The articles contained in the following documents have become this standard when they
are quoted herein. For the dated documents so quoted, all the modifications (excluding
corrections) or revisions made thereafter shall not be applicable to this Standard. For the
undated documents so quoted, the latest editions shall be applicable to this Standard.
GB/T 1032 Test procedures for three-phase induction motors
GB/T 5171 General technical requirements for small power motors
GB/T 9651-2008 Test procedures for single-phase induction motor
3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
general purpose motor
The motor designed and manufactured in accordance with standard rated value. Its
operating characteristics and mechanical structure apply to general operating conditions,
and shall not be limited to a certain specified purpose or a certain type of purpose.
3.3
target minimum allowable values of energy efficiency for motors
After this Standard has been implemented for certain years (Translator’s Note. see clause
4.4 for the exact number of years), the minimum standard value allowed for efficiency of
motor.
3.4
evaluating values of energy conservation for motors
The minimum standard value of motor efficiency which meets the requirements of energy
conservation certification, under the testing conditions specified by this Standard
4 Technical requirements
4.1 Basic requirements
Safety of motor shall be in accordance with GB 12350.
Performance of motor shall be in accordance with GB/T 5171 and in compliance with
relevant product standards.
4.2 Energy efficiency grade of motor
Energy efficiency grade of motor is divided into 3 grades - Grade 1 is the highest grade of
energy efficiency. Under the rated power output, the efficiency of each grade’s motor shall
not be less than those specified in Tables 1 to 5.
4.3 Minimum allowable value of energy efficiency for motor
Under the condition of rated power output, the minimum allowable values of the energy
efficiency of motor shall not be less than Grade 3 specified in Tables 1 to 5.
4.4 Target minimum allowable value of energy efficiency for motor
Under the condition of rated power output, the target minimum allowable values of the
energy efficiency of motor shall not be less than Grade 2 specified in Tables 1 to 5.This
value will be started to implement (Translator’s Note.
4.5 Evaluating value of energy conservation for motor
Under the condition of rated power output, the evaluating value of energy conservation for
motor shall not be less than Grade 2 specified in Tables 1 to 5.
5 Test Method
For a small-power 1-phase asynchronous motor, measurement of efficiency shall be
carried out directly in accordance with GB/T 9651-2008.
